Line Image Buffering for Curved Path Capture Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld image capture devices experience image deformation when the movement path is curved, and existing methods require large storage memory, leading to increased manufacturing costs.
Innovation Solution
The method involves recording position information of each line image, calculating fill information, and directly filling line images into an image buffer to output a product image, effectively addressing deformation and reducing memory usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a temporary buffer and output buffer are used to continuously capture and store line images, then the image capture process can be completed, but a very large amount of storage memory is occupied, increasing manufacturing cost
Solution Approach 1:
The patent extracts and removes the temporary buffer from the system architecture. Instead of using a separate temporary buffer to store all captured line images before processing, the invention directly processes captured images into the final output buffer, eliminating the need for large temporary storage memory while maintaining complete image capture functionality
Solution Approach 2:
The patent merges the functions of the temporary buffer and output buffer into a single integrated processing approach. By combining capture and output operations into one direct flow, the system reduces memory requirements while ensuring reliable image capture completion
2Adaptability or versatility
If the movement path of the handheld image capture device is a curve, then the device can capture images along curved paths, but the original image in the temporary buffer will be bent or even be deformed, making it impossible to pick the correct accessed image
Solution Approach 1:
The patent applies preliminary geometric transformation calculations to determine the correct mapping relationships before images are captured along curved paths. By pre-calculating transformation parameters based on the curved movement path, the system can directly place images into their correct positions in the output buffer, preventing deformation before it occurs
Solution Approach 2:
The patent changes the coordinate system parameters and transformation parameters to accommodate curved movement paths. By dynamically adjusting transformation parameters based on the captured device trajectory, the system maintains image geometric accuracy even when capturing along curves, eliminating bending and deformation issues

AI summary
An image capture and output method comprises steps of providing an image capture device, continuously capturing a plurality of line images from an initial position and recording a position information corresponded to each line image, calculating the difference between the position information of the first line image and the initial position and the differences between the position information of each of the rest line images and a former one of the line image to obtain a fill information, filling each line image into an image buffer according to the fill information, and outputting the image buffer as a product image. Therefore, the deformation issue is effectively solved, the storage memory is saved, and the manufacturing cost is lowered.
